acc aim. (emu-") v The invention relates to mechanismftor selectivelyreproducing and automatically, repeating sound record material.

The object of the present invention is to 'provide mechanism adapted forassociation with a numerical indexior the selection 01 portions of asound record and of reproducing and auto-.

- curately limited in its travel from such point in "only the desired orselected portion of a sound record may. be reproduced and automaticallyrep the spiral or feed groove of the record so'that peated according tothe wishes of the operator.

A further object or the invention is to provide micrometer graduatedmanually operable adjusting or setting means corresponding with thenumber of the grooves of a sound record so that portions of a soundrecord in accordance with the indications on a numerical chartcorresponding to the sound record may be easily selected and themechanism adjusted so that the reproducer stylus will start on therecord at the desired point indicated by the chart and will beautomatically lifted from the record and returned to the selectedinitial starting point after having traversed the desired area oi therecord to automatically repeat all or the selected portion of the soundrecord as long as desired.

A further object of the invention is to provide repeat mechanism havingmeans for returning the tone arm to its initial starting position whichwill be entirely inactive and have no effect on the tone 'arm while thesame is in contact with the sound record so that no extra burden will beplaced on the tone arm or the reproducer stylus and there will be noliability of causing increased wear or other injury to the sound record.

Another object of the invention is to provide repeat mechanism adaptedto lift the tone arm and the stylus from the record before the means iorswinging the tone arm to its initial or selected starting position ispermitted to function so that the means for swinging the tone arm backto its initial position will not cause the reproducer stylus to exert anincreased pressure on the walls of the feed groove of the record.

It is also an object 01' the invention to equip the repeat mechanismwith adapted when the tone arm is swung backwardly and returned to itsinitial starting position to positively hold the tone arm againstswinging movement in either direction until the stylus is low-' ered tothe soundrecord thereby insuring substantial accuracy in returning thetone arm "to its initial position in each operation of the repeatmechanism'.

A further object oi! the invention is to provide in addition'to' themanually operable micrometer latch mechanism adjusting or settingmechanism simple and eifective' means for permitting a flnal adjustmentof the tone arm to compensate for variations in the starting points ofsound records so that adjustments made from a chart may correspond withthe material on sound records irrespective oi variations in the startingpoints of the material on such records.

A further object 01' the invention is to provide the reproduction andcause the tone arm and the reproducer stylus to be mechanically returnedby the mechanism of the reproducer to its initial,

starting position and the needle to be lowered at such point upon thesound record for repeating the previously reproduced area of the soundrecord, thus enabling the reproducer needle to be set for starting soundreproduction at the desiredpoint on the sound record and the soundreproduction to be manually stopped at the desired point with theoperation of the repeat mechanism otherwise automatic.

With these and other objects in view, the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings and pointedvout in the claims hereto appended, it being understood that variouschanges in the form, proportion and minor details of construction,within the scope of the claims, may 'be resorted to without departingfrom the spirit or sacrificing any of the advantages of the invention.

In theaccompanying drawings in which ,is illustrated the preferred embodimentsof the invention I designates a cabinet or casing of a sound reproducingmachine which may be of any desired construction as the presentinvention is applicable to various types of sound reproducing machinessuch as an ordinary phonograph or .a sound reproducing means having anamplifying unit and equipped with a crystal or magnetic pick-up. Thesound reproducing machine includes a turntable 2 actuated by an electricmotor 2* and adapted to receive a sound record 3 having the usual feedgrooves 4 which are engaged in the ordinary manner by a stylus 5 of thetone arm 6, whereby the rotation of the sound record through its spiralfeed groove carries the tone arm inwardly over the record in the usualmanner for reproducing the sound of the record.

The term grooves of the sound record refers to the number ofconvolutions or the pitch to which the spirally grooved record is out.As the sound reproducing machine may be of any desired construction andas the present invention is applicable to all types of sound reproducingmachines detailed illustration and description thereof are deemedunnecessary. It

will be understood that the term tone arm comprehends any form ofhorizontally swinging or swinging movement on an upright spindle ill.The spindle I0 is suitably secured at its lower end to a tiltablesupport Ii which is oscillated vertically by means hereinafter describedfor raising and lowering the tone arm and the reproducer stylus to liftthe stylus from the sound record and to return the stylus to the record.-When the tone arm is in its lowered position the spindle I0 issubstantially vertical and the supporting arm 8 is disposed at a slightinclination and extends upwardly and outwardly from the sleeve 9 asclearly illustrated in Figs. 2 and 4 of the drawings.

While two forms of the invention are illustrated in the accompanyingdrawings as hereinafter fully explained these forms differ from eachother principally in the means for actuating the tiltable support forraising and lowering the tone arm. The parts of the two forms of theinvention which are identical have the same reference character and asingle specific description of such parts is deemed ample.

The tone arm 6 is provided in its top'adjacent its inner end with anopening [2 through which the upper end of the spindle l0 projects andthe outer end of the supporting arm 8 is provided with an enlargement 13in which is threaded for vertical adjustment a tone arm lifting screw llwhich engages the tone arm and lifts the same from the record when thesupport II is tilted from the approximately horizontal positionillustrated in Figs. 2 and 4 of the drawings to the inclined positionshown in Figs. 3 and 5. When thetone arm is lowered to the sound recordand is in the position illustrated in Figs. 2 and 4 of the drawings thetop portion of the tone arm clears the lifting screw and floats free ofthe same to enable the reproducer stylus to engage the grooves of thesound record in the usual manner. The adjustment of the lifting screw Hof the arm 8 is adapted to enable the tone arm to be adjusted to enableits reproducer stylus to operatively engage records of differentthicknesses and the adjustment of the screw I will enable the properclearance between the screw and the tone arm to be provided for thispurpose.

The supporting arm 8 is provided at the pivot I with hollow spacing lugsl5 through which the pivot I passes and which spaces the sides of thetone arm 6 from the supporting arm 8 as clearly shown in Fig. 1 of thedrawings. The

lower end ii of the spindle is threaded for the reception of a nut l1and is secured to a bearing bracket l8 which is arranged upon the upperface of the tiltable support ll. Also the threaded lower end of thespindle l0 and the nut I! provide convenient means for securing a lowerbearing bracket ill to the tiltable support.

The tiltable support may conveniently consist of a substantially oblongplate provided with upstanding reinforcing side flanges 2|) andarranged, in a substantially oblong opening 2| in aosnass a supportingframe 22 which may be of any desired construction. In practice thesupportdrawings and when the platform is in a -hori-' zontal positionthe front 'end 23 rests upon and is supported.- by the adjacentportion-of the supporting frame 22. v The tiltable support whichconstitutes a platform is plvotaliy mounted on the supporting frame atopposite sides by suitable pivots 24 which are mounted in suitable ears25 of the supporting frame and which pierce the side flanges 20 of thetiltable support but the tiltable support may be pivotally mounted inany other desired manner as will be readily understood.

The bearing bracket II which is fixed to the central portion of thetiltable platform supports a worm actuated toothed segment 26 which islooseon the, spindle for rotaryadjustment by a worm 21 to changetheposition of a normally stationary adjustable contact carrying bracket26. The worm actuated segment 26 constitutes a support which is mountedfor horizontal rotary or oscillatory movement on a vertical axis. The

segment 26 which is provided withan arcuate series of teeth 29 to meshwith the worm 21 rests upon the upper face of the bearing bracket l8 andthe bearing bracket I6 is provided at its rear end with transverselyalined bearings 33 in which is mounted a worm shaft 3| having the worm21 fixed to it. The worm shaft 3i extends laterally beyond one side ofthe tiltable support II and has mounted on it a micrometer graduateddrum 32 for theadjustment of the worm actuated segment 26. When thedrumis rotated rotary movement will be imparted to the worm actuated segment26 throughthe worm 21 and after adjustment the worm will form a lock tomaintain-the worm actuated segment 26 and the contact carrying bracket26 in their adiustment.

The micrometer graduated drum is provided at its outer end with a milledflange 33 to facilitate manual operation and it is provided with aspiral groove 34 which is engaged by projections 35 of an indicator 36.The spiral face portion 31 of the drum between the grooves is providedwith numbered graduations 38 corresponding with the grooves of the soundrecord 3 so that each groove of the sound record corresponds with agraduation of the drum 32. The spiral disposition of the face portion 31provides a continuous graduated portion of the drum face of sufficientlength to enable amply spaced grad uations on the drum to correspond tothe closely arranged grooves of the sound record 3. 'In practice a 12inch sound record will have approximately 400 grooves. The number ofgrooves of a 12 inch sound record may vary but 400 is generally themaximum number of grooves of such a record and the particularconstruction of the micrometer graduated drum will enable an excess of400 graduations of the drum to be spaced a sufficient distance apart tobe readily viewed so that the drum may be manually operated withprecision for'positioning the normally fixed adjustable contact carryingbracket at the desired point as one of the determining factors forenabling the desired amount of the sound record material to beautomatically and continuously repeated as hereinafter fully ex plained.

The indicator 36 which is curved to conform to the cylindricalconfiguration of the drum fits flat against the graduated portion of thesame and. preferably consists of a plate provided between its ends witha transverse sleeve 33 which is slidably mounted on a fixed transverseguide rod 43. The projections 35 which engage the spiral groove atopposite sides of the spiral graduated face portion 31 of the drum mayconsist of pins or any other suitable means and the indicator which isslidable laterally on the transverse guide rod 46 when the drum isrotated is provided with a window 4| and it has an indicating member orarrow 42 consisting of an integral projecting portion of the indicatorand extending inwardly at one side of the window and tapered to a pointwhich cooperates with the graduatlons of the'drum. The guide rod 43which is of a length to extend .across the spiral graduated portion 31of the drum is carried by a supporting bracket 43 which may be securedto the tiltable support in any desired manner. The micrometer graduateddrum 32 is preferably located at the left hand side of the tiltablesupport looking toward the tone arm in Fig; 1 of the drawings but thearrangement may be changed if desired, and the lower peripheral portion01 the I ly mounted on the same for free rotative movement incident tothe swinging movement of the tone arm which is adjustably positioned bythe means hereinafter described with relation to the upper bearingbracket 46. The bearing bracket 46 provides a support mounted on avertical axis for horizontal rotary or swinging movement to permitactuation of the tone arm by the sound record. The upper bearing bracket46 has fixed to it a movable contact carrying bracket 48 which swingstoward and from the fixed contact carrying bracket as the tone arm iscarried over the sound record in reproducing sounds therefrom and whenthe tone arm is raised from the sound record and is swung outwardly toreturn it to its initial starting position. The upper bearing bracket isprovided at opposite sides with transversely alined bearings 49 in whichis mounted a transversely disposed worm shaft'5ll. A worm which is fixedto the Worm shaft 50 meshes with a worm actuated segment 52 providedwith an arcuate series of teeth 53 which mesh with the worm 5| asclearly illustrated in Fig. 1 of the drawings. The worm actuated segment52 is provided with a central opening 54' actuated segment 52 andextends into the sleeve.

9 of the supporting arm 8. The sleeve 3 of the supporting arm 8 isarranged on the extended portion of the sleeve 55 and is supported uponthe upper face of the worm actuated segment 52. The supporting arm 8 andthe tone arm 6 are connected with the worm actuated segment 52 and therotary movement or adjustment of the segment .52 by the rotary movementof the worm 5i adjusts the tone arm and arranges the same in the desiredposition with relation to the bearing bracket 46 so that when thebearing bracket is carried to its initial or starting position the tonearm will be positioned at the desired point on the sound record forstarting the reproduction of the desired portion of the same. The wormBI is pinned or otherwise fixed to the worm shaft 58 which extendslaterally from the right hand side of the laterally tiltable support inFig. 1 of the drawings and it has flxedly mounted on it a manuallyoperable micrometer graduated drum 58 constructed the same as the drum82. The drum 58 is provided at the outer end with a milled flange 51 andit has a spiral groove 58 defining a spirally arranged surface 58provided with numbered graduations 68 corresponding to the grooves of asound record. A laterally slidable indicator 8| cooperates with thegraduations 60 of the spirally disposed peripheral surface of the drumand is of the same construction as the indicator 36 heretoforedescribed.

The indicator GI which may be constructed of any suitable material isprovided with a sleeve 82 and it has projections 83 located at oppositesides of it and formed by pins or other suitable means. The projections63 extend into the spiral groove 58 and cause the indicator to movelaterally on a transverse guide rod Bl when the drum is manuallyrotated. The transverse guide rod 84 which extends across the face ofthe drum in spaced relation thereto is mounted at its inner end in abracket 65 which is fixed to the upper bearing bracket 46. The slide iiis provided at the spirally graduated portion 59 with a window 66 and ithas an indicating member or arrow 61 preferably formed by an integraltapered portion of the slide. The arrow li'l pro- :lects inwardly withrespect to the window and is located at the graduations 58 of the drum.The spiral arrangement of the graduated portion of the face of the drumis of sufficient length to enable the graduations to be readily seen andto be from to the required number necessary to correspond to any sizerecord or pitch to which the grooved record is out. As before explainedthe maximum number of convolutions or grooves of a 12 inch record isapproximately 400 and the graduations of the drum 56 are numbered from 0to 400 and are continued slightly in excess of the latter, as clearlyillustrated in Fig. 1 of the drawings.

If a 12 inch record was cut to 650 pitch per 4 inches or less than 400pitch per 4 inches then the graduated drum would not correspond but thechart would indicate the approximate number to dial to lower needle tothe position on record and chart would further show the position to dialrepeat drum for repetition.

This will be ample for the standard 12 inch records but it will bereadily understood that the spiral graduated portions of the drums 32and 88 may be made of any desired length to provide ample space for thegraduations to correspond to the pitch to which any desired size ofrecord may be out.

When the micrometer graduated drum 32 is turned to a given number inregister with the arrow 42 in the window of the indicator 38 above theface of the drum 32 it will place the reproducer needle in a selectedposition above the related record groove of the sound record 3 on theturntable.v By means of the worm 5! of the segment 52 the tone arm isactuated at a speed less than that of the drum; The other micrometergraduated drum 55-when turned to any given number from a zero positionadvances the contact carrying bracket 28 ahead of the contact carryingbracket 48 and spaces it from the said contact carrying bracket 48 and,when the reproducer needle is lowered into the record roove theturntable must make the number of revolutions indicated in they window88 of the slide 8| of the micrometer graduated drum 88 before thecontact carrying bracket 83 reaches the contact carrying bracket 28 andcloses a motor circuit 88 for lifting the tone arm and the reproducerneedle from the sound recor as hereinafter fully explained.

when the tone arm is lifted from the sound record by the tilting of thesupport II and is swung outwardly with respect to the record to theselected initial or starting position it is while elevated locked insuch initial position by a. latch 68 pivoted at 10 to a fixed bracket IIand engageable with a keeper recess 12 of a latch engaged member I3rigid with and carried by the upper bearing bracket 48. The fixedbracket H is mounted on the supportingframe 22 and may be secured to thesame in any desired manner. As illustrated in the accompanying drawingsit is arranged at the front of the supporting frame and it extendsupwardly and inwardly over the front portion of the tiltable support.The pivot Ill of the latch 89 is located adjacent one end of the latchand the bracket is provided at opposite sides of the vertical plane ofthe pivot ill with stops H and which limit the swinging movement of thelatch. The latch engaged member 13 may be connected with the upperbearing member 48 by means of the contact carrying bracket 48 or by anyother suitable means. It is provided at its front or outer portion withan arcuate flange 18 arranged to receive the latch 89 when the frontportion of the tiltable support II is elevated and the latch rides onthe flange l6 during-the return movement of the tone arm and drops intothe keeper recess I2 as soon as the tone arm reaches its selectedinitial position.

The flange 15 is provided at the outer side of the keeper recess 12 witha projecting portion 11 which forms a stop shoulder for accuratelylimiting the movement of the latch engaged member and the tone arm inone direction for insuring the return of the tone arm to its preciseselected initial position. In Fig. '7 of the drawings the latch 69 isshown supported by the flange 18, the tone arm being elevated asillustrated in Fig. 5 of the drawings. In Fig. 8 the latch 68 is shownin engagement with the keeper notch 12 for squaring the tone arm withrelation to the sound record so that the reproducer needle 5 will belowered to the precise point selected for starting the playing orreproduction of the sound record.

In Fig. 9 of the drawings the latch 69 is shown clear of the keeperrecess 12, the tone arm having been lowered to engage the reproducerneedle with the sound record 3 as illustrated in Fig. 4 of the drawings.1

The tiltable support II is adapted to be locked in its tilted positionwith the latch 68 in engagement with the keeper recess I2 by means of amanually operable locking lever 18 pivoted at 18 in a bracket 88 fixedto the rear' portion of the supporting frame 22. The pivot 19 is locatedadjacent to one end of the manually operable locking lever 18 to form atoe or engaging portion 8! which is adapted to be swung downwardly fromthe full line position shown in Fig. 5 to the dotted line positionillustrated in the said figure for locking the outer or rear portion ofthe tiltable support in its lowered position.

This locking of the support II in its tilted position will maintain thesame rigidly in such position while the tone arm is held rigidly againstswinging movement by the engagement of the latch 68 with the keeperrecess 12. This will facilitate accurate adjustment of the tone arm andthe adjustable contact carrying bracket although such adjustment may ofcourse be made without looking the tiltable support. Also the lockinglever is adapted to be manually operated for lifting the inner or frontportion of the tiltable support II and the tone arm carried thereby andfor causing a manual operation of the mechanical means hereinafterdescribed. for returning the tone arm to its initial position with! outclosing the motor circuit 68 and independently of the same so that undercertain conditions a motor and motor circuit and contact carryingbrackets may be omitted to provide an inexpensive manually operablerepeat mechanism for sound reproducing machines.

,In addition to the adjustment or positioning of the tone arm affordedby the micrometer graduated drum and the connections between the sameand the worm actuated segment 52 final adjustment means is provided topermit the tone arm to be adjusted to compensate for variations whichmay occur in the starting point of a sound record so that the tone armmaybe adjusted with relation to any particular sound record and thereproducer needle of the tone arm will when lowered to the sound recordcorrespond exactly with the numbered graduations of the drum 56.

The upper worm actuated segment 52- is provided at the front or innerportion with lugs 82 and 83 spaced'apart to receive a dependingextension 84 of the supporting arm 8. The extension 84 is preferably inthe form of a lobe, as clearly illustrated in Fig. 5 of the drawings,and the arm 83 is provided at the outer side with a laterally extendingtubular barrel 85 closed at the outer end and containing spring meansfor urging the supporting arm inwardly with respect to the lug 83. Thespring means preferably consists of a plunger 86 and a coil spring 81.The plunger extends through the lug 83 and the other lug is providedwith an adjusting screw 88 having a threaded engagement with the lug 82.The lobe 84 of the supporting arm 8 is preferably provided at each ofits side faces with an indentation 88 to receive either the inner end ofthe adjusting screw 88 or the engaging end of the plunger 86. Theadjusting screw 88 is adapted to move the supporting arm away from thelug 82 and towards the lug '83, the spring actuated plunger 86 yieldingto the action of the screw. The screw is also adapted to be adjusted topermit the spring actuated plunger to move the supporting arm awayfromthe lug 83 and towards the lug 82. By the means of the screw and thespring actuated plunger the supporting arm 48 which carries the tone armmay be adjusted from the central position in the space between the lugs82 and 83 to either of the said lugs and a rela-- tively smalladjustment at the inner or pivoted end of the supporting arm 8 willafford a relatively large adjustment of the reproducer needle at theouter end of the tone arm sufficient to amply compensate for variationsin the starting point of sound records.

The upper bearing bracket 46- with which the tone arm is adjustablyconnected is provided at opposite sides with laterally alined shoulders88 arranged to be engaged by side portions 8| of a forked lever 82fulcrumed on the depending bracket l8 at a point intermediate of itsends by a transverse pivot 88 and having a lower arm 84 arranged to becarried into engagement with a stop 86. The lever 82 is reinforced byside flanges 82 and the pivot 88 passes through the side flanges 82' andthe sides of the bracket l8 which-is approximately U-shaped inhorizontal section. The stop 86 preferably consists of a bracket mountedon the supporting frame 22 at the bottom'thereof and arranged in thepath of movement of the lower arm 84 and adapted after being engaged bythe arm 84 to hold the same against further movement whereby the uppertilting of the inner or front portion of the the upper bearing bracketand a swinging movement of the tone arm and returns the same to itsselected starting position. The other side of'the forked portion of thelever 82 engages with theother shoulder at the completion of theswinging movement of the tone arm and the upper bearing bracket issquared or returned to its initial position and is locked in suchposition by the latch 68' until released from such locked position bythe downward movement of the inner. portion of the tiltable support.

Instead of employing a bracket 85 anyother suitable means may beprovided for holding the lower arm 84 of the forked lever for causing anengagement of the same with the side shoulders of the. upper bearingbracket. Also while the side shoulders 88 of the upper bearing bracket46 are illustrated in the drawings as formed by integral laterallyextending portions of the said bearing bracket 48 any other suitablemeans may be employed for providing the side shoulders to cooperate withthe forked lever for returning the bearing bracket and squaring orcentering the same at the completion of such return movement.

The front elevated portion of the tiltable support when free to. move ismoved downwardly by a coil spring 86 which'lowers the tone-arm and thereproducer needle to the sound record.

In Figs. 2 and 3 of the drawings an electric motor 81 is employed forfurnishing the energy for tilting the support It to elevate the inner orfront portion thereof and-raise the tone arm and,

. bracket l8 and carrying at its lower end a roller 88 which cooperateswith a rotary cam 88 actuated by the electric motor 8'l. The roller 88which is preferably mounted in a forked or bifurcated portion of the arm81* is held against the periphery of the cam 88 by the spring 86 andwhen the cam is rotated-and carried from the position illustrated inFig. 2 of the drawings to that shown in Fig. 3 the support ll istiltedfrom the horizontal position illustrated in Fig. 2 to the inclinedposition shown in Fig. 3. When the cam 88 is rotated from the positionshown in Fig. 3 to that illustrated in Fig. 2 the spring brings thetiltable support from the tilted by a roller I02 of a mercury switchI03pivotposition shown in-Fig. '3 to the horizontal position illustratedin Fig. 2, the cam controlling the action of thespring inmoving thetiltable support from its inclined. position to its normal horizontalposition. Thecam 99 is mounted on' a cam shaft. I which is connectedwith the motor shaft by suitable speed reducin gearing (not shown). Y

The cam shaft also carriesa switch control-.

ling cam IOI which is engaged at its periphery ally mounted at- I04 onthe main frame 22 at thebottom thereof and engaged by a spring I05 acut-out I06 of substantially segmental form' which maintains the rollerI02 in contact with the periphery of the switch controlling cam IOI. Theswitch controlling cam IOI is provided with presenting a concaveperipheral edge to the roller I02 and permitting thespring I05 to tiltthe mercury switch and cause the mercury to flow to the end remotefrom'the contacts I01 for opening the motor .circuit 68. The mercuryswitch is arranged in-parallel with contacts I00 .and I09 mounted on thecontact carrying brackets 28 and 48 and operates through the cam IOI tomaintain the motor circuit closed until after the complete separation ofthe contacts I08 and I09 when the tone arm is swung outwardly withthrough the operation of the spring 96 and the cam 99, the motor circuitbeing opened and the motor stopped when the cut-out I06 of the cam iscarried to the roller I02 of the mercury switch and the latter tilted tocarry the mercury thereof from the contacts I01 to the opposite end ofthe mercury switch. The cut-out I06 permits the spring I05 to swing thecontact carrying end of the mercury switch upwardly a sufficientdistance to arrange the mercury switch in an inclined position oppositeto that illustrated in Figs. 2 and 3 of the drawings. The contacts I00and I09 are insulated from the contact carrying brackets 28 and 48and'the arrangement of the said contacts in parallel with the mercuryswitch is indicated diagrammatically in the motor circuit in Fig. 18 ofthe drawings.

In Figs. .4'and 5 of the drawings is illustrated another fo'rm of theinvention in which a solenoid, H0 is employed instead of an electric mo-'tor for supplying rotary motion. The solenoidwhich is preferablyarranged in a vertical position isvprovided with a vertically movablecore III and constitutes a-motor for furnishlng.re-'

- minates at a point above the plunger extension H2 of the core III. Thetilting movement of the support II under the influence of the spring H3is controlled by a dashpot Ill of the ordinary construction. The dashpotII4 which is arranged vertically is pivotally mounted at its lower endat H5 in the supporting frame at the bottom thereof and its plunger H6is pivotally connected at the upper end at ill to the outer portion ofthe tiltable support II at the lower face of the same. Also a coiledspring H0 is head I I9 formed on the upper end of the plunger I16 forthepivotal connection between the plunger and-the tiltable support. Whenthe spring 3 is fiexediby the closing of the motor or solenoidcircuitthe, inner portion .of the platform is elevated'with a controlledmotion and the forked lever 92 operatesin the manner heretoforedescribed to return the tone arm and the reproducer needle to theselected initial position. The contact carrying arms 28 and 40 of theform of the invention illustrated in Figs. 4-6, inclusive, carrycontacts I 20 and I2I and the bracket 40 also carries a mercury switchI22 arranged in parallel .with the contacts I20 and I2I of the solenoidcircuit and pivotally mounted at I23 in a yoke I2 secured to an arm I25extending laterally from the contact carrying bracket 40.

The solenoid circuit is the same as the motor ;circuit with theexception of the solenoid being substituted for the motor. Detailedillustration of the solenoid circuit is deemed unnecessary. The pivotalconnection between the mercury switch and the yoke is formed by spacedpivots I23 passing through gears I26 of a lever I21.

. The lever I21 isfulcrumed intermediate its ends and its inner armcarries a spring clip I28 for holding the, mercury switch I22 and theouter arm is engaged by a switch controlling member I29 havinganattaching flange I20 secured to the supporting frame. -The switchcontrolling member I29 consists of an approximately horizontal platenormally located above the front arm I30 of the lever I21 and when theInner portion of the tiltable support is elevated to the positionillustrated in Fig. 5 of the drawings the lever I21 is swung on itspivotal connection I23 and the mercury switch is tilted to close thesolenoid circuit and will maintain the solenoid circuit closed as asolenoid circuit after the separation of thecontacts I20 and'I2I andprevent arcing of the same. The mercury switch I22 maintains thesolenoid circuit closed until the contact carrying arm 48 and the tonearm are returned to their initial or starting position. This movementalso carries the arm I30 of the lever I21 beyond the switch controllingmember I29 and permits the mercury switch to tilt automatically from theinclined position shown in Fig. 5 of the drawings to the oppositelyinclined position illustrated in Fig. 4 for causing the mercury of theswitch to leave the contacts I3I of the mercury switch and open thesolenoid circuit and deenergize the solenoid.

The springs I I3 and IIS insure the return of the tiltable platform toits normal horizontal position illustrated in Fig. 4 of the drawings.

The operation of the repeat mechanism of the form of the inventionillustrated in Figs. 4 to 6, inclusive, of the drawings is the same asthat of the form of the invention illustrated in Figs. 2 and 3 of thedrawings and the movement of the tiltable support II is controlled topermit a smooth and gentle operation of the mechanism in raising thetone arm from the sound record and in swinging it horizontally to itsselected initial position and in lowering .the tone arm and thereproducer needle to the sound record. The micrometer graduated drum atthe right hand side of Fig. 1 of the drawin s is set with the arrow orthe indicator at for starting the playing 01' the sound record 3 at thebeginning thereof and the arrow or the indicator of the left handmicrometer graduated drum in Fig. 1 oi the drawings is set at 400. Thissetting will cause the entire sound record to be played and continuouslyreproduced. The micrometer graduated drums may be operated to set theindicator at any point between 0 and 400 on each drum so that anyportion of the sound record 3 may be played and automatically repeatedcontinuously. In practice a numbered index sheet I3! is designed to beprovided for each sound record and these may be conveniently bound in aloose leai binder as indicated at I33.

The upper right hand corner oi one oi the sheets is shown in Fig. 11 onan enlarged scale. These numbered index sheets which correspond with thegraduations of the micrometer drums enable the tone arm to be adjustedfor starting the playing 01' the record at the desired point and theadjustment oi the normally stationary contact controlled by themicrometer graduated drum 3! will enable the desired portion of thesound record to be played. Also if desired the normally stationaryadjustable contact which .is controlled by the micrometer drum 32 may beset at the limit or its adjustment and only the tone arm adjusted toselect the desired starting point on the record. The record may then beplayed and the tone arm may be raised and we played portion repeated byoperating the locking lever II which when swung from the position shownin full lines in either Fig. 2 or Fig. 4 oi the drawings to the dottedline position illustrated in the said figures will elevate the frontportion of the tiltable platform and lift the tone arm from itsassociation with the sound track of sound record and return the tone armto its selected starting position. The locking lever may then beoperated to release tiltable support and permit the tone arm to belowered to the sound record for repeating the previously played portion01' the record. In this manner the repeat mechanism may be manuallycontrolled without the electrical means for the automatic operation 01'the repeat mechanism.

In order to enable the micrometer graduated drum to be set in the properposition with relation to the worms the outer end portion of each of theworm shafts is split at I and is provided with a bore I35 threaded atits inner portion I36 and tapered at I3'I at its outer split portion.The threaded portion of the bore is located beyond the split portion andis adapted to be engaged by the threaded portion I33 ofv a screw I39which is provided beyond the threaded portion I38 with a tapered portionI40 located at the head end of the screw and adapted to engage the wallsof the tapered portion I31 of the bore of the worm shaft for expandingthe same within a hub I4I' of the micrometer graduated drum. In practicethe micrometer graduated drum which may be constructed of any suitablematerial is provided at its ends with heads having suitable bearings forthe worm shaft, the bearings being preferably in the form of hubs orenlargements but a any other suitable construction may of course be 'beprovided for this purpose as well as raised characters for the blind toenable the blind to mechanism. The numerical designations prei'- erablyconsist of the letter R and a number. These may be arranged whereverrequired or desired to show where the micrometer graduated drum iii ofthe repeat mechanism is to be set for repeating the selected subjectmatter of the sound record related to the subject matter of the chart.The numbers on the chart for positioning the tone arm will designate thestarting point for any selected area or a sound record so that the chartwill have starting and finishing numbers of any section of the soundrecord desired for reproduction and repetition, the numbers on the chartbeing related to both drums as well as the sou volutions or grooves ofthe sound record for all or any portion 01 the record selected forreproduction and repetition.
